Advances in treatment for postpartum major depressive disorder.

Introduction: Postpartum depressive disorder (PPD) is a burdensome medical condition. To date, only one treatment (Brexanolone) has undergone registrational trials and is approved in the United States with an indication for the treatment of PPD. However, other treatments are prescribed and have been tested for this condition. Herein, the authors review the available scientific evidence pertaining to the somatic treatments of PPD. Areas covered: The authors evaluate the published open-label and randomized controlled trials (RCTs), examine the biological mechanisms of PPD treatments, and evaluate how the available data translates into information that may be useful for clinical practice. Expert opinion: Antidepressants have long been the mainstay of PPD treatment, despite the limited evidence from randomized clinical trials that supports this practice. Brexanolone improves treatment options for women with PPD. However, the relatively burdensome administration and monitoring protocol, along with the high cost of the medication, limit the possibility for an extensive use of this medication. Large, randomized, controlled trials of hormonal treatments in patients with PPD are warranted. Also, treatment with mood stabilizers and/or antipsychotics in women with major depressive disorder, who meet the DSM-5 mixed features specifiers in the post-partum period, should be tested in controlled clinical trials.

Drug safety evaluation of aripiprazole in bipolar disorder.

Introduction: Safety and tolerability of medications are key variables to inform treatment choice for patients with bipolar disorder (BD). This review focuses on the overall tolerability and safety profile of aripiprazole when used for its bipolar disorder indications, which include acute treatment of manic and mixed episodes and maintenance treatment of bipolar I disorder for the oral formulation, agitation associated with bipolar mania for the injectable immediate-release formulation, and maintenance treatment of bipolar I disorder for the long acting once-monthly (AOM) formulation. Areas covered: The authors reviewed aripiprazole safety in bipolar disorder according to product labeling. English language reports located through PubMed and information available on the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) websites, with a focus on the safety and tolerability of aripiprazole, were reviewed. Expert opinion: Compared to many other antipsychotics, aripiprazole has a relatively favorable tolerability profile, with a lower risk for weight gain, dyslipidemia, diabetes, and hyperprolactinemia. Compared to first-generation antipsychotics, and similar to most second-generation antipsychotics, aripiprazole has a reduced propensity for extrapyramidal side effects and a better cardiovascular safety.

Pharmacotherapeutic strategies for treating binge eating disorder. Evidence from clinical trials and implications for clinical practice.

INTRODUCTION: Binge eating disorder (BED) is the most common eating disorder and was newly recognized in 2013 in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). BED is frequently associated with obesity and the metabolic syndrome, as well as with other psychiatric diseases, such as mood (49%), anxiety (41%), and substance use (22%) disorders. BED is highly prevalent and carries a high burden of mental and physical illness and disability. However, BED is frequently under-recognized and under-treated. AREAS COVERED: This paper reviews the main pharmacological treatments for BED and provides an expert opinion based on the available evidence and on the authors' clinical experience with patients affected by BED. EXPERT OPINION: Several medications have proven to be effective for the treatment of BED, including Lisdexamfetamine (LDX), topiramate as well as anti-anxiety and antidepressant medications. To date, LDX is the only FDA approved medication for BED. Consequently, as a general rule, the use of an FDA approved medication should always be preferred. However, when in the presence of concomitant psychiatric conditions such as anxiety or depression, other medications that have proven efficacy in those comorbid conditions can be used and may contextually provide a benefit for BED.

The Microbiome: A New Target for Research and Treatment of Schizophrenia and its Resistant Presentations? A Systematic Literature Search and Review.

Background: The gastrointestinal system hosts roughly 1,800 distinct phyla and about 40,000 bacterial classes, which are known as microbiota, and which are able to influence the brain. For instance, microbiota can also influence the immune response through the activation of the immune system or through the release of mediators that are able to cross the brain blood barrier or that can interact with other substances that have free access to the brain, such as tryptophan and kynurenic acid, which is a metabolite of tryptophan and which has been involved in the pathogenesis of schizophrenia. Objectives: This paper reviews the possible relationships between microbiome, schizophrenia and treatment resistance. Given the possibility of a role of immune activation and alterations, we also describe the relationship between schizophrenia and immune inflammatory response. Finally, we report on the studies about the use of probiotic and prebiotics in schizophrenia. Methods: Cochrane library and PubMed were searched from the year 2000 to 2018 for publications about microbiome, immune-mediated pathology, schizophrenia and neurodevelopmental disorders. The following search string was used: (microbiome or immune mediated) AND (schizophrenia OR neurodevelopmental disorder). Associated publications were hand-searched from the list of references of the identified papers. A narrative review was also conducted about the use of probiotics and prebiotics in schizophrenia. Results: There exists a close relationship between the central nervous system and the gastrointestinal tract, which makes it likely that there is a relationship between schizophrenia, including its resistant forms, and microbiota. This paper provides a summary of the most important studies that we identified on the topic. Conclusions: Schizophrenia in particular, remain a challenge for researchers and practitioners and the possibility of a role of the microbiome and of immune-mediated pathology should be better explored, not only in animal models but also in clinical trials of agents that are able to alter gut microbiota and possibly influence the mechanisms of gastrointestinal inflammation. Microbiome targeted treatments have not been well-studied yet in patients with mental illness in general, and with schizophrenia in particular. Nonetheless, the field is well worth of being appropriately investigated.

Using sertraline in postpartum and breastfeeding: balancing risks and benefits.

INTRODUCTION: The World Health Organization recommends newborns to be breastfed but this may be challenging if the mother needs to be treated for depression, since strong evidence to inform treatment choice is missing. AREAS COVERED: We provide a critical review of the literature to guide clinicians who are considering sertraline for the management of depression during postpartum. EXPERT OPINION: Sertraline is one of the safest antidepressants during breastfeeding. In most cases, women already taking sertraline should be advised to breastfeed and continue the medication. We recommend to begin with low doses and to slowly increase the dose up, with careful monitoring of the newborn for adverse effects (irritability, poor feeding, or uneasy sleep, especially if the child was born premature or had low weight at birth). The target dose should be the lowest effective. When feasible, child exposure to the medication may be reduced by avoiding breastfeeding at the time when the antidepressant milk concentration is at its peak. A decision to switch to sertraline from ongoing and effective treatment should be taken only after a scrupulous evaluation of the potential risks and benefits of switching versus continuing the ongoing medication while monitoring the infant carefully.

Smoking cessation in a homeless population: there is a will, but is there a way?

This cross-sectional study sought to determine the prevalence of smoking, readiness to quit, and preferences for smoking cessation treatments among a sample of 236 homeless adults attending 9 sites serving homeless persons (mean age 41.8 years; 73% male). Two thirds (69%) were current smokers, of whom 37% reported readiness to quit smoking within the next 6 months. In bivariate analyses, persons were significantly (P <.05) more likely to be ready to quit if they had tried to quit in the past and if they had social support to quit smoking. Nicotine replacement was the most commonly preferred assistance method (44%), and self-efficacy to quit (10-point scale) was significantly greater if assistance was available (7.3 vs 4.9; P <.001). The findings suggest an urgent need to develop and implement smoking cessation programs for homeless persons.
